Fairchild Semiconductor Unveils Motion-Smart Power Modules
Fairchild Semiconductor International Inc. (South Portland, ME) unveiled its new Motion-Smart Power Modules (SPM™), which offer an integrated solution for low-power (below 100 W), brushless dc motor applications. The Motion-SPM devices integrate multiple functions in a single compact package, offering a simplified motor drive solution to speed engineering design, reduce PC board space, and enable energy-efficient and reliable designs in home appliances.
The Motion-SPM multi-chip modules combine six fast-recovery MOSFETs (FRFET™) and three half-bridge, high-voltage ICs in one thermally efficient, ultra-compact (29 mm x 12 mm) Tiny-DIP package designed for brushless dc motors with built-in control. Each Motion-SPM uses advanced FRFET and high-voltage IC devices to ensure the performance and long-term reliability of the end product, while simplifying motor inverter designs. The Motion-SPMs' FRFETs optimize system efficiency by lowering switching and conduction losses during low-current conditions.
For ruggedness, the modules provide a wider reverse bias safe operating area than IGBTs of similar ratings. By using the MOSFETs' body diodes as free-wheeling diodes, the Motion-SPMs eliminate the need for additional components, improving the efficiency and noise immunity. The gate-driver ICs increase reliability through high-isolation, 5 V CMOS/TTL interface and under-voltage lockout protection features.
The FSB50250 (500 V/2 A) is priced at $7.20, and the FSB50450 (3 A) is priced at $8.26. Each is housed in a 23-lead DIP. The products are lead-free. Availability now, delivery is 12 weeks ARO.
